Disaster management and the creation of hazard maps are activities that come to minimize the damage caused by disasters through processes to prevent the destruction and degradation of the environment. Floods represent one of the most dangerous disasters and are frequently encountered in different areas of the Earth's surface. The causes of these phenomena can be natural or the result of inappropriate exploitation of human activities. Among the most frequent causes of flooding are heavy rains, storms or melting snow. The present research evaluated remote sensing methods and techniques combined with the science of geographic information systems in the analysis of floods in the Western area of Romania, as well as in the estimation of the areas affected by these floods. The studied area is located near the town of Lugoj in Timis county - Romania. Radar images (SAR) taken from the Sentinel-1A remote sensing system were used to analyze and create maps of the flooded areas. The images are not influenced by weather conditions and can be taken both during the day and at night, which provides a good source of high-resolution datasets. In conclusion, this study can provide answers to the reason for the expansion of floods in the studied area and to a more rigorous planning in order to reduce and manage risks in periods of high flood risk.
